I had heard that it was possible to dye yarns using black beans but have never tried it before so last week when I went grocery shopping I looked for some. I purchased a 500 gram bag of Turtle Black Beans from my local Waitrose grocery store.
I placed all of the beans into a large plastic jar and covered them with ordinary tap water. Overnight, the beans expanded and filled the whole jar, so then I split the bean solution into 2 jars and added more water. I let this bean stock sit on my kitchen counter for 3 days. The water in the jars started to look quite blue so I was hopeful that this would work.
Meanwhile, I spun 100 grams of white wool and divided the wool into 2 50 gram skeins.
